Apparatus for processing element configuration, apparatus and method for device configuration, apparatus for high-speed device configuration, program, and non-transitory computer-readable storage medium

摘要

An apparatus, method, and system is described herein for fast device configuration. Fast configuration devices may be configured without host intervention. For example, before going into a low power mode, the device may dump its configuration context to storage and go to sleep. Then, upon resuming into an active state, a controller can reload the context without a host processing device having to re-write the entire configuration space, which potentially reduces the latency decision of when a device goes into a low power mode. Moreover, fast configuration mechanism may accelerate configuration accesses from the host by providing accelerated completions, while still ensuring legacy configuration for legacy devices.
